At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.
There are a lot of companies in the auth space, but we feel like we have something special:
* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

We are a DIY distribution and promotion platform for independent artists and labels. In an industry that's notoriously over-complicated and dominated by players who only care about volume, we're building something kinder: a genuinely helpful way to release music and build a following.
We already support more than 20,000 users in their music careers. In the Netherlands, we're a leading provider of independent digital music distribution, and we continue to grow steadily on an international scale.
We are actively looking for a senior full stack engineer and a medior operations and automation engineer. Unfortunately we can’t offer relocation or visa sponsorship.
Our stack relies on python, fastapi, postgres, next.js, react, typescript, gcp, terraform, k8s, redis, dataflow, see job descriptions for more details.
Check out https://kb.makewaves.fm/general/careers for more details.
We build UCS, an omni-channel contact-center platform used by Dutch housing corporations and municipalities. Profitable, ~40 people, 15+ years in market. Our platform runs reliably but the way we operate it is behind 2026 standards. You'd own that gap: moving from PowerShell-script deploys toward infra-as-code, real observability and clean deployment automation. First hire in a new platform team, growing to 3-4 people.
Reality check: it's a .NET-on-Windows/Azure shop (IIS, Windows services, SQL Server), so pure Linux/K8s/Go isn't the fit. We deliberately don't run Kubernetes (tens of tenants, office-hours workloads); Ansible + Compose-per-VM is the likely direction. We prefer simple and boring. Light, fair on-call.
Basic Dutch a plus, not required. No recruiters please.

Tower is a Python-native serverless data platform. Data teams write plain Python, and we handle packaging, dependency resolution, scheduling, and execution across a serverless runtime built on Apache Iceberg. There's no clusters to manage, no YAML to write, no pipelines to rewrite to fit someone else's engine. If you've ever wanted your local Python script to just run in production at scale without a Databricks detour, that's the product.
We're a small, senior team split between London and Berlin. We've built a lot of tech: Custom run dispatch service, multi-region routing, storage based on Apache Iceberg, and the runtime itself, to name a few. This is deep systems work--things like scheduling, distributed execution, and performance. We're not gluing SaaS together.
Stack: Go and Rust for the platform, Python everywhere it matters, Kubernetes (EKS + Karpenter) on AWS, RDS Postgres, ElastiCache Redis, S3/Iceberg, WorkOS for auth.
Looking for:
* strong distributed-systems fundamentals
* comfort owning a system end to end
* taste for correctness under load
Bonus: data-platform, query-engine, or Iceberg experience; async Rust; Kubernetes internals.

Ecosmic is on a mission to reduce threat exposure in space by building software for Space Situational Awareness. To achieve this, we built a team of flight dynamics engineers and computer scientists to build & package in-house algorithms into easy-to-use, reliable, and secure products. As an example, our platform recently allowed us to identify a series of close approaches in GEO involving Russia's Luch/Olymp-2 and a Western telecommunications satellite, possibly attributed to SIGINT activity.
We're hiring a Senior DevOps Engineer (mid-level candidates are welcome too!) to aid the effort of unlocking on-premises deployments of our algorithms with Kubernetes, and to contribute to the evolution of our platform.
Our stack includes Python for backend services and high-level algorithm tooling, C++ for performance-critical components, AWS for cloud infrastructure, and Terraform for IaC. We currently use managed serverless services, and we’re beginning a gradual migration from C++ to Rust for its reliability guarantees.
